Can a gift of land or property given freely, without any conditions, be taken back by the person who gave it? Or can the gift be contested by someone after the giver passes away?

In India, a freely given gift of land or property becomes the recipient’s absolute property, meaning the giver cannot take it back. However, if there’s evidence of undue influence or fraud during the gift process, the gift could be contested by someone after the giver’s death, possibly leading to its revocation.
